descr
|
|
The Xerces-Perl module is implemented as a shared object. It needs
|
|
some symbols from libgcc.a, such as __eh_alloc. It's not possible
|
|
to link the xerces-P shared object with libgcc.a, because libgcc.a
|
|
is not compiled with -fPIC. Hence we need to have the missing
|
|
symbols in the Perl executable.
|
|
This hack includes the whole libgcc.a in the Perl executable, and
|
|
links with c++ so that some mandatory symbols such as __pure_virtual
|
|
are also included. It should go away with GCC-3.0, or if we make a
|
|
libgcc.so on day.

Oddly this does not occur using the mipspro compiler. Possible

reason: using gcc we have longer CFLAGS. Fix: add USE_GNU_TOOLS+=awk

iff IRIX and gcc. Problem: this might affect other packages as well.

One might consider depending libtool on gawk for IRIX.

Apparently, for as of yet undetermined reasons, gawk as built on IRIX
|
|
under pkgsrc croaks on regular expressions including a combination of
|
|
alpha- and numerical matches, such as the rather trivial
|
|
/^[ \t]*[0-9]+/
|
|
Let's use the system's AWK (ie nawk) for this package to avoid
|
|
breaking hundreds of dependents.
|
|
Speculation: somehow the regular expression library used to build gawk
|
|
conflicts with the systems regular expression library or some such.
|
|
Note: gawk from SGIs freeware collection depends on expat -- why is
|
|
that? Does that have anything to do with anything?
